Dr. Gao was a villain who always worked together with Victor Krane. They loved creating armies together, and both harbored a desire to wipe out the human race. Dr. Gao liked androids. The second time Krane died, Dr. Gao begged for his life back. However, Krane's body was gone. Gao decided to allow Krane to inhabit half of his body. Thus, Dr. Victor Gao-Krane was born. After Krane's 3rd death, Dr. Gao continued to be a major threat throughout season 2, until he and his android army were killed one last time. Gao was also the person who resurrected Ricardo. He joined forces with Janet Smythe to kill the team.
